Application filed November 23, 1922. Serial No. 602,908.

To all whom it mayconcem:

Be it known that I, TADEUSZ ZDRODOW- sin, a citizen of Poland, residingat Pittston, in the county of Luzerne and State of 6 Pennsylvania, haveinvented certain new and useful Improvements in File Sheaths, of whichthe following is a specification.

This invention relates to certain new and useful improvements in filesheaths and has particular reference to a casing of elongated form forhousing the blade of a file to protect the file sheath during shipment.

The primary object of the invention is to provide a sheath for fileswherein the sheath casing is provided with a fabric lining with a hingedsection carried by the casing to facilitate positioning of the liningtherein. With the above and other objects in view as the nature of theinvention is better understood, the same consists of the novel form,combination and arrangement of parts hereinafter more fully described,shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designatecorresponding parts throughout the several views,

Figure 1 is a perspective view of a file sheath constructed inaccordance with the present invention, the file being shown in positiontherein,

Figure 2 is a crosssectional view taken on line II-II of Fig. 1 showingthe hinged section of the sheathing,

Figure 3 is a fragmentary top plan view,

Figure 4: is a fragmentary perspective view of the open end of thesheath with the hinged section moved to open position,

Figure 5 is a perspective view of the open end of a modified form ofsheath showing the fabric lining retained -by the beaded edges of thesheath casing,

Figure 6 is a fragmentary perspective view of the closed end of thesheath, and

Figure 7 is a detail sectional view of the form of the invention shownin Figs. 5 and 6 illustrating the inwardly directed bead carried by thesheath for frictionally engaging the faces of the file blade.

Referring more in detail to the accompanying drawing, and particularlyto Figs. 1 to 4, there is illustrated a file sheath embodying a casinghaving a bottom wall 1, integral end walls 2 and 3 and an integral upperwall section 4, the sheath being preferably constructed of sheet metaland bent into the cross-sectional formation shown in Fig. 2, one endbeing closed and the other end open as shown in Figs. 1 and 4 for thereception of the file F. f

The upper wallsection 5 has one edge thereof flanged to provide an endwall section 3 adjacent the lower end wall 3, said end wall sections 3-and 3 being longitudinally hinged as at 6 and clearly shown in Figs. 2and 3. The connection between the adjacent edges of the upper wallsections 4 and 5 includes struck-out spring fingers 7 carried by thefree edge of the wall section L that are adapted to be received inopenings 8 formed in the adjacent free edge of the upper wall section 5,the spring fingers 7 resiliently retaining the hinged cover section 5 inthe closed position shown in Fig. 2.

A fabric lining 9 is provided for the sheath, one edge thereof beingengaged by spurs 10 carried by the free edge of the cover section 1 andcompletely covering the inner face of the sheath, the hinged coversection 5 being primarily provided to permit the proper positioning ofthe lining 9 within the sheath, while the file F is positioned thereinby being slid through the open end thereof.

In the form of the invention shown in Figs. 5 to 7, the sheath isconstructed of a single sheet ofmaterial bent into the desired shapewith the meeting edges. of the upper wall sections 45 and 5 formed intoa bead 11 to be so retained, the indentures 12 in the bead forming asubstantial locking connection between the adjacent edges. The fabriclining 9 covers the inner face of the sheath and has the edges thereofsecured in the bead 11. To prevent accidental displacement of the file Ffrom the sheath, the side and end walls thereof adjacent the open end,as shown in Fig. 5, are provided with an inwardly pressed rib 13 thatfrictionally engages the file F for the purpose intended.

While there are herein shown and described the preferred embodiments ofthe present invention, it is nevertheless to be ing secured at themeeting edges by said bead, said bead having depressions formed thereinfor locking said edges, and an in- Wardly pressed rib formedin the Wallsof i the casing adjacent the open end forfrictional engagement with afile.

In testimony whereof I aflix my signature.

TADEUSZ ZDRODOWSKI.
